7.4 VFD unit
High voltage remains in capacitors in the output circuit of the VFD unit.
•
WAIT AT LEAST 10 MINUTES after VFD unit is de-energized, and then confirm that the
•
capacitors have fully discharged by measuring the voltage between braking module
terminals
The VFD unit (hereinafter — unit) drives the turbine motor.
The unit is supplied from input terminals (1), see Fig. 8. Control panel (2)
allows to change parameters of the unit. Motor is connected to output
terminals (4). Braking module terminals (3) might be used to control
residual voltage in the output circuit of the unit.
To see and change parameters of the unit, follow these steps:
1. To change or view a parameter value, press
reads 00
2. Press
e. g. 02

Unit settings chart is given in Table 1.
NOTE 1: Some settings can be changed only when the unit is stopped.
NOTE 2: Once parameter 00.02 set to 9, VFD display reads 'End', and then gets back to the
main indication mode. After this, continue setup process from parameter 00.03.
NOTE 3: Parameters not listed in the chart should not be modified.
and ; it should be less than 25 Vdc.
or to choose the first two digits of the parameter,
again, display reads 02.00
or to choose the second two digits of the parameter, e. g. 02.11
again to see the current value of the parameter. If needed, change the value
or .
to confirm and save the new value, the display reads End
to return back to the previous level of selection or to the main mode.
